Co-gasification of coal char and biomass char was conducted to investigate the interactions between them. And random pore model (RPM) and modified random pore model (MRPM) were applied to describe the gasification behaviors of the samples. The results show that inhibiting effect was observed during co-gasification of corn stalk char with Hulunbeier lignite coal char, while synergistic effects were observed during co-gasification of corn stalk char with Shenmu bituminous coal char and Jincheng anthracite coal char. The inhibiting effect was attributed to the intimate contact and comparable gasification rate between biomass char and coal char, and the loss of the active form of potassium caused by the formation of KAlSiO4, which was proved to be inactive during gasification. While the synergistic effect was caused by the high potassium content of biomass char and the significant difference of reaction rate between coal char and biomass char during gasification.
进行了煤焦与生物质焦的共气化实验，以研究它们之间的相互作用。并应用随机孔模型（RPM）和修正随机孔模型（MRPM）来描述样品的气化行为。结果表明，在玉米秸秆焦与呼伦贝尔褐煤焦的共气化过程中观察到了抑制作用，而在玉米秸秆焦与神木烟煤焦和晋城无烟煤焦的共气化过程中观察到了协同作用。抑制作用归因于生物质焦与煤焦之间的紧密接触和可比的气化速率，以及由 KAlSiO4 形成导致的钾的活性形式的损失，在气化过程中被证明是不活跃的。而协同作用则是由于生物质焦中的高钾含量以及气化过程中煤焦和生物质焦之间的反应速率的显著差异所致。
